Open Source Summit Europe 2026 Call for Proposals Closes on 24 June 2026

Proposals for Open Source Summit Europe 2026 close at 23:59 CEST (UTC+2) on 24 June 2026. The Linux Foundation event is scheduled for 7 October 2026 to 9 October 2026 in Prague, Czechia. Submissions are being handled through Sessionize.

The event is a broad open-source conference rather than a Drupal-specific gathering. Its relevance for Drupal readers lies in participation, speaking, and cross-project visibility. The programme gives contributors a venue to present work that connects Drupal practice with wider open-source topics such as governance, documentation, security, cloud infrastructure, and AI.

The call for proposals lists tracks across cloud and orchestration, Digital Trust, Embedded Linux Conference, Linux, Open AI + Data, Open Source 101, OSS enabling and management, standards, technical documentation, packages, images and containers, PX4, safety-critical software, and Zephyr. Suggested topics include infrastructure-as-code, container runtimes, supply chain security, open models, AI agents, retrieval-augmented generation, documentation processes, open-source governance, and security management. CFP notifications are scheduled for 24 July 2026, with the schedule announcement listed for 29 July 2026.

Submission formats include session presentations, panel discussions, Birds of a Feather sessions, tutorials, lightning talks, and Linux-only hackathon sessions. The CFP notes that reviewers must be able to assess a speaker’s subject-matter expertise from the proposal. It also says proposals relying heavily on AI-generated or templated content may lack the specificity needed to evaluate technical depth.

The CFP page asks submitters to avoid sales or marketing pitches and discussion of unlicensed or potentially closed-source technologies. Accepted speakers receive one complimentary event pass per accepted submission. Accepted speakers are also required to submit slides before the event.

Registration lists attendee pricing at €590 through 4 August 2026, €760 from 5 August 2026 to 21 September 2026, and €1,010 from 22 September 2026 to 9 October 2026. Academic and hobbyist passes are listed at €230, while small business passes are listed at €420. Registration includes conference content, networking activities, the Solutions Showcase, LF project mini-summits, applicable co-located events, and access to on-demand sessions.

The event schedule lists co-located events on 5 October 2026 and 6 October 2026. Keynotes, breakout sessions, and the Solutions Showcase are scheduled from 7 October 2026 to 9 October 2026. The CFP announcement provides broad open-source participation details, but it does not present the programme as Drupal-specific.
